Green-robed senators of mighty woods

This week has been all about oaks, Keats’ “green-robed senators of mighty woods”. In Richard Powers’ extraordinary novel, ‘The Overstory’, the collaborative endurance of the quercus genus is counterposed to the transient destruction of homo sapiens. I had been eking the book so that I could finish it on holiday surrounded by trees, rather than tower blocks, and so yesterday I allowed myself to turn the last page after a wonderful autumnal stroll around the Glanusk Estate in the Brecon Beacons, made all the more magical by being able to enjoy it with my parents.
